| Abstract: | Fatigue failure is one of the most common types of failure during low voltage apparatus life test. Reasonable structure design is basic to ensure the fatigue life of machine parts. The fatigue failure phenomenon in the life test of switch-disconnector was expatiated through theoretical calculation,Algor simulation software of finite element analysis and experimental validation. The structure of switch-disconnector was optimized and verified based on the results of the analysis. |
